Hamiltonian Monte Carlo

Riemannian Manifold Hamiltonian Monte Carlo Link to this paper

As part of the Computational Statistics course taught by S. Allassonnière, I worked on a generalization of Hamiltonian Monte Carlo. We implemented in Python the Riemannian Manifold Hamiltonian Monte Carlo algorithm along with HMC and other baseline algorithms, and empirically compare performances on a Bayesian logistic regression problem.

Guided Policy Search

Policy Search: A review Link to this paper

This is the result of a project part of the Reinforcement Learning course taught by A.Lazaric. This project's goal was to write a review on Policy Search, a reinforcement learning's sub-field which proceeds by directly learning a parametrized policy without estimated any value function.

Factorial hidden Markov models

Factorial Hidden Markov Models Link to this paper

I studied in depth the factorial hidden Markov models article wrote by Zoubin Ghahramani and Michael I. Jordan as part of the Probabilistic Graphical Model course taught by Guillaume Obozinski and Francis Bach. Factorial hidden Markov models are an extension of classical hidden Markov models with a distributed representation of their state's space.

Gaussian process bandits

Gaussian Process Bandits with Thompson Sampling Link to this paper

As part of the Graphs in ML course taught by Michal Valko, I proposed and implemented a Thompson Sampling algorithm for the Gaussian Process bandit setting. This setting is described in Gaussian Process Optimization in the Bandit Setting: No Regret and Experimental Design.

Bicycle sharing system

Research Internship: Urban mobility data analysis Link to this paper

During an internship at Ifsttar, I applied probabilistic models such as LDA, along with web visualizations, to transportation’s data in order to enhance the understanding of commuters’ behavior.

Mixture of experts

Learning from crowds Link to this paper

As part of the Introduction to Machine Learning taught by taught by Guillaume Obozinski, we studied and reimplemented two articles dealing with the supervised learning multiple annotators setting: Modeling annotator expertise: Learning when everybody knows a bit of something and Learning From Crowds.
